Add Content of a library to a Report

I have a Report-File CustomView.rptdesing and a Library-File Space.rptlibrary.
The File Space.rptlibrary has as content only one Label.
 
The File CustomView.rptdesing has as content only a grid. 
I want now to add after this Grid of CustomView.rptdesing the Content of the file Space.rptlibrary.
 
This is my corresponding source-code
<pre class="_prettyXprint _lang-">
public class PrintReport {

private final static String BIRT_HOME = "C:/dev/libraries/birt-runtime-4_4_1/ReportEngine";
private final static String LOG_DIR = "./birt/logs/";

PrintReport printReport;
printReport = new PrintReport();
printReport.generateFile();
} catch (BirtException e1) {
// TODO Auto-generated catch block

}
}

public PrintReport() throws BirtException {

engineConfig.setEngineContext(context);
try {

.createFactoryObject(IReportEngineFactory.EXTENSION_REPORT_ENGINE_FACTORY);
reportEngine = reportEngineFactory.createReportEngine(engineConfig);

designEngine = designEngineFactory.createDesignEngine(designConfig);
session = designEngine.newSessionHandle(ULocale.ENGLISH);
} catch (BirtException e) {
e.printStackTrace();
reportEngine.destroy();
}

}

reportDesignHandle.includeLibrary(LIBRARY, "LL");
DesignElementHandle dehSpace = libraryHandleSpace.findElement("Space");

reportDesignHandle.getBody().add(dehSpace);
=> !!!get here the error!!!

I get the following error:
